UNITED STATES PATENT OFFICE} PIERRE JOSE BOUCHiEB, OIE CHELSEA, LONDON, ENGLAND.

COVER OR STOPPIEN FOR JARS, PUTS BOTTLES, AND OTHER RECEPTAGLES.

Specification of Letters Patent.

Patented Mar. 5, 1918.

Application filed October 21, 1914. Serial No. 867,888.

['0 all whom it may concern:

Be it known that I, Prnuun Josn BoUoHnn,

in thin sheet metal or equivalent material of covers of the same form as those usually made of glass, earthenware, or other solid material. Not only are the covers made ac cording to this present invention much lighter in weight but they are cheaper to manufacture and they possess the further advantage of being applicable to receptacles the mouth of which is irregularin form.

Referring to the drawings which form part of this specification,

Figure 1 shows in perspective the upper domed part of the stopper, with adownwardly extending flange formed around its edge. a

Fig. 2 shows in perspective the lower hat shaped part of the stopper.

Fig. 3 shows in perspective the two parts shown in Figs. 1 and 2 assembled and with the flange of the upper part closed down.

Fig. 4 shows the stopper in diametrical section.

Fig. 5 shows in perspective, the bottle neck, stopper and retaining band disasseciatcd. a

Fig. 6 shows in perspective the bottle closed and sealed with my improved stopper.

To carry the invention into effect I take a disk of metal a and by stamping pressure :form a downwardly extending flange 5 around its edge and raise the central portion 0 into a domed formation thereby producing the stamping illustrated in Fig. 1;

Into the space inclosed by the downwardly extending flange b I dispose a stamping of hat formation as illustrated in Fig. 2 Which has a flange a? of considerable width and a central substantially cylindrical portion c of smaller diameter; the flange b beingbeaded down upon the flange (i so as totightly hold the two parts together and produce a stopper substantially as illustrated in Fig. 3, having a flange with a certain amount. of flexibility relative to said stopper.

In practice I prefer to raise the upper part of the stopper as shown in the section illustrated-in Fig. 4 as thereby less lodgmeat for dust and dirt is provided.

A cover or stopper formed as hereinbetore described has a plug portion 6 adapted to fit the neck f of the receptacle and a laterally extending flexible flanged portion 9 adapted to form a supporting surface for a cork, rubber or other closing washer and cause it toconi'orm to the upper surface of the neck of the receptacle.

It will be seen that owing to the flexible nature of the laterally extending flange g a hcrmetical joint can be readily made on receptacles having irregular necks without by having its lower edge turned under the rim of the said neck, the stopper being maintained in position with sufficient pressure to cause hermetioal sealing.

I claim A closure for jars or the like comprising a stopper, a horizontal annular flange formed on said stopper and corresponding in width to the width of the top Wall of the neck of a receptacle to which it is applied, said flange being formed of flexible material and arranged to rest on the top wall of the neck of a receptacle when said stopper is in position, a ridge formed on the underside of said flange at its marginal edge, a washer interposed between said flange and the top wall of the neck of the receptacle, and means for clamping said flange in engagement with the neck of a receptacle, in a direction parallel to the axis 01' the neck.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
